1) One more than 136.
2) ROUNDED OFF inverse of the fine structure constant (0.007297351 +/- 0.000000006), which is a product of two physical constants and measures the strength with which subatomic particles interact with one another and with light. Appreciated by physicists but not physicians.

The room number for the lounge in the Physics department is 137, in honor of the fine structure constant.

number that has become widely known to emo kids to have much to do with love. Originated in the 1995 movie "Empire Records" where one character must tell the other he has feelings for her at exactly 1:37PM

used in reference to the movie Empire Records where AJ is to tell Corey he loves her at 1:37pm

Lucas: That's an excellent time.
